Thats the next part i will change if the ignition coil doesnt sort it.
As for the coil, it should be hear tomoz, but the person who sold me it originally sent me the wrong item which he doesnt want back 
So anyone need a Relay Solenoid ?

Re: Bike wont rev ?
Its sorted now !!! 
I got the ignition coil through the post this morning ... replaced the old one and didnt make much of a difference.
I had a feeling it was running lean hence the backfiring so i put the clip down a notch and fired it up are a few seconds i could rev it
More responsive than it was with the old coil. but it was lean all along.

Re: Bike wont rev ?
Grrrrr  its playing up again.
ive changed the oil, new coil.
it idles near enough perfect but jumps about slighty, and when i rev it slowly the revs will pick up but it still back fires till about half throttle and the it revs okay.
Any ideas ?
Also the carb needle is slightly bent and out of shape could this effect it ?

Re: Bike wont rev ?
yeah carb needle being bent would of course affect it. Go get a new one.
could still be the mixture out slightly.
